Definitions
- the present disclosure is directed to bearing and bearing assemblies, particularly the present disclosure is directed to a steering yoke assembly.
- a steering wheel can be mechanically coupled to a pinion gear via steering shaft.
- the pinion gear can include gear teeth that are mated with teeth on a rack shaft. As the pinion gear rotates, the rotational motion can be translated into linear motion at the rack shaft.
- the rack shaft can be connected to a tie rod at each wheel assembly. As the rack shaft moves linearly, the tie rods can rotate in order to rotate the wheel assemblies and turn the vehicle.
- a steering yoke assembly can be used to provide a biasing force that forces the shaft into the pinion gear.
- the yoke may also be referred to as a “yoke assembly,” “yoke slipper,” or “puck.”
- the rack shaft typically steel
- the rack shaft slides along the yoke when the pinion gear is rotated.
- Proper fit between the steering yoke and the rack shaft is essential to any rack and pinion steering system.
- EP 1 743 826 A1 describes a gear with a gear rod slidably received in a housing with a pressure piece controlled in a guide, the guide or piece having an elastic unit to press a wall region of the piece against a wall of the guide, and shows the following features of claim 1: a steering yoke bearing assembly, comprising a body, comprising: a first end having a flat surface; a second end opposite the first end, the second end having a surface having a first lateral side and a second lateral side opposite the first lateral side and first and second bearing pads.
- a steering yoke assembly can include a yoke body comprising a first material and a pair of bearing pads affixed to an arcuate, or curved, surface, such as a concave surface, that is configured to fit at least partially around an outer wall of a generally cylindrical shaft.
- the bearing pads can be made from another material such as a low friction material and can extend from the arcuate surface of the yoke assembly in order provide limited contact between the steering yoke assembly and the rack shaft.
- the arcuate surface can be formed with a pair of bearing pad pockets and each bearing pad pocket can be configured to receive a bearing pad.
- a bearing pad can be press-fitted, glued, or otherwise installed and affixed, within each bearing pad pocket.
